Color deficiency or better known as color blindness is a hereditary disorder. Although color deficiency is more common in males, females are able to obtain the disorder. But the males carries the color deficient gene.
If a male is colourblind the phenotype could not be seen by other humans, but by colour blind tests. ( You know thosesm tests that theres a number hidden in the image and you can't see the number if your colourblind). Most of the time colour blind males look like everyone else.
Homozygous recessive for the color blindness gene

It would be the mother you would be interested in. My optometrist told me that the color blindness gene is carried by the mother.
The genotypes of a mother of colorblind man may be x* x or x* x*. The * depicts the gene responsible for colorblindness.

A male grasshopper's genotype is XO. A female grasshopper's genotype is XX. X represents the presence of a sex chromosome, and O represents the lack of a sex chromosome.
The ratio of a human baby being a male to being a female is 1:1.That means that the baby has a 50% of being a male, and a 50% of being a female.A male human has the genotype of XY.A female human has the genotype of XX.Some mutated organisms have an XXY or XYY for a genotype.
XX for female and XY for male. -anonymous18_K
All the sons would be color-blind and none of the daughters are color-blind.
In the ZW sex chromosome system, the male genotype is ZZ. The letter Z represents the presence of a dominant male-determining gene, while the letter W represents the absence of this gene, which determines female development. Therefore, individuals with the ZZ genotype develop as males in this system.
you can't predict that. it depends on what sex the offspring is. if it is a female, she could be color blind because her father is, but a male could be color blind either way. because color blindness is carried on the Y chromosome and not the X chromosome.
The genotype for a male is XY. A female is XX. The 23rd homologous pair is the sex gene that determines this.
50% probability that the sons produced from this union will be color blind. 50% probability that a son will not have the disease. 50% probability that a daughter will be a carrier of the allele for color blindness. 50% probability that a daughter will not be a carrier. Phenotypically this would be 1male color blind, 1 male not color blind, 1 female carrier and 1 female non-carrier. Assuming that the probability of male and female offspring is identical...this would be 25% of each genotype mentioned above. Based on phenotype, without regard to sex the percentages of normal to colorblind would be 75% to 25% with the 25% displaying the characteristic all being male.

If the male parent has genotype AS and the female parent has genotype AA what is the offspring?

go to the zoo, pick up an anole and study it closely like a scientist would, and look at its color the male will be brown and the female will be red.if you are color blind then you might want to look at its eyeball. the male will have 5 pupils the female will have 21. if you are blind then feel its fur, the male will have only have 3 little sploches of hair, and the female will just have no hair. if you lost your hand in the civil war and you are also color blind or blind then you just have no luck so go to your mommy, cry it all out and get a life.
at the moment of conception when the male and female gametes fuse together. at the moment of conception when the male and female gametes fuse together.
For the case of the human, an individual with XX genotype is female. Other organisms have different ways of determining sex.
it generally could if someone who was a male or female was color blind too. Like if your a boy.... and the person who was color blind was a girl then you might have gotten it from her.. usually you get stuff from the opposite sex then the same sex in a situation like this... there's nothing to be woried about.. this just means that you are more like the other sex then you are your own...

Color blindness is carried on male genes only.
